A famous slogan from 1956 was ‘faithful and relentless as a Sherpa’. Virtually no expedition to the Everest and neighbouring mountains could do without the Sherpas - even today.

It’s the heart that ticks

Every timepiece created by Sherpa Watches has a story.
Because every watch is hand built and represents the craftmanship of all the German and Swiss watch makers, case manufacturers, dial creators and mechanical engineers involved. Their love for the iconic watches that explored oceans and conquered Mount Everest in the 1950s reflects in every detail.
We combine the revolutionary watch case designs from the past with modern techniques and the highest quality materials to ensure our watches will stand the test of time.

Sherpa Watches is dedicated to bringing back the most legendary watch models. We relaunch designs that have become true treasures among vintage watch collectors and offer something remarkable for anyone who has yet to discover the Sherpa heritage. Sherpa Watches pays tribute to the achievements of the old Enicar S.A. brand that conquered the watch world during the golden age of tool watches. And at the same time, we honour the humble Sherpa people that inspired the Swiss pioneers in naming their most ambitious model line from 1956 on.

Iconic design meets state of the art engineering.
Imagination meets perfectionism.
Devotion meets emotion.
It’s not only mechanics that makes Sherpa Watches tick.

It’s a heart.

Sherpa Ultradive and OPS

We are proud to introduce the first two Sherpa Watches models, now available for pre-order: the Ultradive and the OPS. Both inspired by the models created in the mid-sixties by Lengnau based watch manufacturer Enicar S.A. and revisited to grace the wrists of everyone with a passion for classic dive watch designs and an eye for quality and durability.

The Sherpa Ultradive and the OPS sport a robust super compressor case that measures 40 mm in diameter, excluding the crowns and crown protection. Both case size and crown protection guards are identical to the original Sherpa models from 1968, just like the revolutionary water-resistant technology as developed by Ervin Piquerez S.A. (EPSA) – yet updated to today’s technologies.

Finally, after more than 60 years, the true ‘Compressor Dive Watch’ will be reborn.

to grace the wrists of everyone with a passion for classic dive watch designs and an eye for quality and durability.

The Sherpa Ultradive and the OPS, wrist favourites of countless professional deep-sea and military divers from the past, cult actors like Alain Delon and now world-famous musicians like Ed Sheeran, sport a robust super compressor case that measures 40 mm in diameter, excluding the crowns and crown protection. Both case size and crown protection guards are identical to the original Sherpa models from 1968, just like the revolutionary water-resistant technology as developed by Ervin Piquerez S.A. (EPSA) – yet updated to today’s technologies.

Even the unique bayonet compressor case back construction, originally named EPSA-STOP, and the re-invented MONOFLEX compressor crowns are present in our Ultradive and OPS to grant you the full authentic ‘Compressor Dive Watch experience’. Finally, after more than 60 years, the true ‘Compressor Dive Watch’ will be reborn.

Mantramatic: the world’s first good vibes watch

Sherpa Watches has embraced the craftmanship and high-quality engineering from the Swiss pioneers. We have made every effort possible to elevate the concepts and techniques from the golden age of watch making into the present. The timeless designs of the Ultradive and the OPS did not need much finetuning, as their look and feel are as outspoken today as they were half a century ago. On a technical level, our watches surpass their predecessors in terms of accuracy, water tightness and durability. And as a world’s first we added a hidden gem of minuscule proportions, for large impact.

The mechanical movement inside the Ultradive and OPS is not a regular automatic. It is a Mantramatic! We microscopically laser engraved a traditional Tibetan Buddhist mantra OM MANI PEME HUNG, which is very commonly used in the Sherpa region on two of the wheels, (using a custom created Tibetan font). Following widespread Himalaya Buddhist tradition used in prayer-wheels, the wheels in the movement rotate constantly, sending out vibes of love, wisdom and compassion from your wrist straight into the world – 30 million times per year. With the naked eye you will not notice the mantra is there. Instead, you will feel it.

The drive for happiness is vital. It’s what keeps us in motion.

Sherpa Watches
and the Sherpa people

At Sherpa Watches, we pay respects to the heritage of the great Sherpa watch models from the past. We also honour the Sherpa people whose reliability and toughness, yet at the same time friendly, relaxed and happy attitude are still well known around the world.

We believe that we should give something back. Sherpa Watches will donate a percentage of every watch sold and give it to a good cause in the Sherpa area in Nepal. We chose “Sagarmatha next” in the Khumbu region and the Nepal Himalaya Sherpa foundation in Kathmandu, both supporting different projects in the Sherpa regions of Nepal.

Virtually no expedition to the Everest and neighbouring mountains could do without the Sherpas. And even when there are no expeditions going on around the high mountains of the region, the Sherpas are active: regular cleaning expeditions, transporting masses of expedition relics, trash, and left debris down from the sacred mountains.

Because we chose to use their name as a brand, and thus profit from their reputation, we believe that we should give something back. Sherpa Watches will donate a percentage of every watch sold and give it to a good cause in the Sherpa area in Nepal. For our first two watch models, we chose “Sagarmatha next” in the Khumbu region and the Nepal Himalaya Sherpa foundation in Kathmandu, both supporting different projects in the Sherpa regions of Nepal.
